sparc-sun-solaris versus sparc64-sun-solaris

I don't think so:
- the Sun compiler produces 32-bit code by default,
- building sparc64-sun-solaris from the Sun compiler requires the user to 
pass a cryptic CC variable to the configure script. Sure this is documented, 
but I'd rather avoid any gratuitous pitfall,
- in my experience, the 64-bit compiler is slower than the 32-bit one on the 
same machine (Ultra-60).
